Arduvision (I): embedded computer vision with arduino

Ok, its time to share stuff again.
I've spent most of this year's (2014) summer learning how to use a CMOS sensor together with an arduino (ATmega328p) microcontroller, in the process of developing some personal projects.
This is the first of a series of articles to publish my experiencies, and hopefully save someone's time.

In this first post, I'll just release the minimal info that may let you start right away experimenting without reading about how things work. In further articles I'll make detailed explanations of the hardware and software, and the decisions and reasons that led me to my current setup. However, at the end of this post, you may find links to useful documentation.

How I solved my SD card corruption problems by modding the Raspberry Pi

I've spent last month struggling (once again, after some trouble with the power) with SD card corruptions due to the Raspberry Pi's "design idiosyncrasy" (a funny name to avoid cursing).
Until I finally found a solution...

Impress Progress Bar



A few months ago I wanted to have a progress bar in an Impress presentation, but couldn't find a feature to generate it automatically. So I had to write a macro script...

Playing with the 3D printer & microfusion metal casting

Today I collected my first microfused things from Fundiart, in  Valencia.
The items were printed in PLA and cast in brass, and the results are excellent.

Climberbots II - work in progress

vlcsnap-2013-09-10-20h41m40s239 So, here we are again, with Climberbot II, of the babelbots project.
Last version was made out of recycled scrap and household stuff. And it worked, partially. But the tracks were not good enough for further development.

Climberbot... climbing!

This is a prototype model made out of household stuff.

The tracks are made out of a kitchen mat and the wheels with bottle caps.
